“…S1). This finding is consistent with the previous observation that phosphorus availability is a key factor regulating the soil microbial community (Liu et al 2018a;Qin et al 2020). Soil nitrogen components, including TN, NO 3 − and NH 4 + , play an important role in regulating soil fungal community composition and diversity, and this finding could be partly caused by the nitrogen-fixing capacity of Robinia pseudoacacia, which results in high NO 3…”

“…Soil fungi underlie a phylogenetic pattern in plant growth responses to nitrogen (N) enrichment (Wooliver et al 2018), and chronic nitrogen additions in a temperate forest fundamentally restructured the soil fungal community (Morrison et al 2016). Similarly, soil phosphorus availability contributes to the abundance and diversity of the soil fungal community (Qin et al 2020). Furthermore, soil microclimates, such as soil moisture (SM) and pH, contribute to intra-annual spatiotemporal changes in fungal community composition and functioning (Castano et al 2018).…”

Aims The objective of this study was to analyze the responses of the soil fungal community to the afforestation of cropland with single and mixed tree species. Methods We investigated changes in soil fungal community composition, diversity, structure and functional groups in the topsoil (0-20 cm) following afforestation. Six forest types were analyzed in this study: Robinia pseudoacacia (RP), Platycladus orientalis (PO), Pinus tabuliformis (PT), Robinia pseudoacacia + Platycladus orientalis (RPPO), Robinia pseudoacacia + Pinus tabuliformis (RPPT), and Platycladus orientalis + Pinus tabuliformis (POPT).Results Soil fungal community composition and diversity significantly varied among cropland and forestland samples. Afforestation generally reduced soil fungal diversity and altered functional groups, and these variations were mainly mediated by tree species. Rare genera play an important role in the soil fungal network among cropland and forestland samples. Soil available phosphorus (AP) explained the largest portion of the variance in the soil fungal community. Soil available nutrients and microclimate were significantly associated with soil fungal diversity and richness. Conclusions Our observations indicate that afforestation of cropland fundamentally restructures soil fungal community composition, structure, diversity and functional groups. Nutrient availability was a principal factor regulating fungal community composition following afforestation.

“…Whilst the role and experimental quantification of AM fungi in plant production in agriculture has often been debated (Ryan, Graham, Morton, & Kirkegaard, 2019), they are undoubtedly an important component of the soil ecosystem (Qin et al, 2020). However, community composition and abundance (root colonization and EMH) of AM fungi can be strongly affected by field management practices (e.g., plastic film mulching, AM fungal inoculation, and fungicide application) (Bi, Wang, et al, 2018; Jiang et al, 2018; Liu et al, 2012).…”

“…AM fungi have been demonstrated to influence SOC by incorporating and transporting C through the extramatrical hyphal length (EMH) (Leake et al, 2004;Leifheit, Verbruggen, & Rillig, 2015), producing glomalin-related soil protein (GRSP) (Dai et al, 2015;Liu et al, 2019), as well as by providing C to the microbial community (Jones, Nguyen, & Finlay, 2009).

Soil labile organic carbon sequestration is tightly correlated with the abundance and diversity of arbuscular mycorrhizal fungi in semiarid maize fields

Plastic film mulching can affect soil organic carbon (C) lability in semiarid regions. Arbuscular mycorrhizal (AM) fungi represent an important route for plant‐derived C into soil and can be influenced by agricultural practices. Whether the changes of AM fungal community affect soil organic C sequestration is a fundamental question in semiarid environments. To this end, we conducted two field experiments investigating the influence of a Funneliformis mosseae inoculation and mycorrhizal‐suppression using benomyl application on maize growth, soil fractions of organic C, AM fungal parameters, including diversity profiling using the Illumina MiSeq. The results showed that AM fungal community composition was significantly altered by plastic film mulching and fungicide applications, soil organic C fractions and nitrogen were most important factors in influencing the AM fungal community. AM fungal inoculation significantly increased particulate organic C and light fraction organic C content, due to enhance dextramatrical hyphal length (EMH), glomalin content, and root biomass. Conversely, fungicide applications reduced labile organic C, possibly through decreasing EMH, glomalin content and soil AM fungal diversity. Increases in relative abundance of F. mosseae in rhizosphere soil, coupled with increases in AM fungal root colonization from F. mosseae inoculation indicates successfully established by outcompeting the existing natural AM fungal community. Plastic film mulching resulted in significant increases in maize yield and water use efficiency, and AM fungal inoculation was found to amplify the effects. Thus, AM fungal inoculation may act as an effective farming practice to improve soil organic C fractions, which can boost maize productivity.

“…The soil condition used in this study was already fertile which combated the effects of mycorrhiza application. High available soil phosphorus (P) status, often limits AM fungal development and results in the C-costs to the host plant outweighing any benefits from AM colonization [20]. Moreover, the intense use of manure as fertilizer also may lead to high soil P concentration [14].…”

A case study in Indonesia of circular bioeconomy implementation was investigated by managing livestock wastes, especially goat manure (GM), which an excess of its availability may be adverse to the environment. The efficacy of this scenario to control pollution or to increase productivity still needs to be proven. Hence, this research aimed to study the possibility of circular bioeconomy implementation using biotic and abiotic resources in Indonesia under excessive nutrients (GM and mycorrhizal) on P. angulata production. Outdoor factorial container experiment was carried out using a randomized complete block design in Central Java, Indonesia. Treatments included four levels of GM (0, 10, 20, 30 g plant−1) and four levels of mycorrhizal (0, 10, 20, 30 g plant−1) applied in the soil with six replications. This case study revealed that the use of mycorrhizal inoculant and GM indicated no significant difference to most of P. angulata’s growth and yield parameters. The implementation of circular bioeconomy through integrated farming of P. angulata was not an instant solution for economic and environmental optimization, but can be considered as a way to tackle environmental problem due to the excessive livestock wastes. The environmental sustainability can be achieved step by step, without hindering farmers’ income.
